Abstract
A man in his late 60s presented with intermittent abdominal pain, nausea, vomiting and approximately 40 pounds of weight loss over the course of a year, most concerning for chronic mesenteric ischaemia. Given a prior negative workup, a CT angiogram was performed and revealed a wide neck mid-superior mesenteric artery pseudoaneurysm (PSA). As PSAs are susceptible to thrombus formation and distal emboli, this incidental finding was considered a possible explanation for his intermittent symptoms and thus required treatment. Anatomical constraints precluded traditional coiling or covered stent placement, so the interventional radiology team used a neurointerventional technique and performed a successful balloon-assisted coil embolisation of the PSA with subsequent resolution of the patient's symptoms. More than 3 years postprocedure, the patient remains asymptomatic with no complications.
